“…But snails were found infested naturally or experimentally with the same size as in our study during which no special conditions were used ( Kariuki et al., 2017 ; Mulero et al., 2019 ; Mutuku et al., 2014 ; Senghor et al., 2015 ; Tchuenté et al., 1999 ). For example, we did not oxygenate the tanks or to provide additional mineral ions which could lower the mortality rate and increase specimen size ( Rodrigues et al., 2020 ). An in-depth analysis of the quality of the different waters used coupled with an intentional variation of their physico-chemical parameters would allow to develop suitable snails breeding medium.…”
